300 WM, 225 Grn Hornady BTHP Match Load Suggestions?

[cowboyarcher]

Hi Guys,

I recently got into the 300 Win Mag caliber and should be able to start load development in the next few weeks I hope. I have a Browning A-Bolt to work with, and the following components:

- Retumbo
- H1000
- H4831SC
- Hornady 225 gr BTHP Match
- Hornady and Win Cases
- WLRM primers.

Does anyone have any suggestions as to COAL these bullets like, or potential accuracy load with these powders? I realize there are a lot of variables here, but I an new to this caliber and just looking form a starting point as the powder will go fairly quickly with this round.

Also, can I just average the Hodgdon data listed for the 220's and the 230's to get a rough idea for the 225's?

Thanks for any help and God bless you fellas,

Adam

Adam,
If you have the H2o case capacity and barrel lenght I'll run some QL's for you with these powders. It will get you in the ballpark. I've shot and loaded a bit of .300 stuff, mostly RUM. I've had great success and accuracy out of target and hunting rifles. Retumbo was my go to powder, but have used others.
